Greatly, bearing is fragile, bearing abnormal noise the shortcomings of, a kind of and submerged pump bearing-transmission structure proposing.
The purpose of this utility model is achieved through the following technical solutions：
A kind of submerged pump bearing-transmission structure of the present utility model, including bearing block, lower bearing, lower axle pressure cap, under
Oil scraper ring, upper oil scraper ring, upper bearing (metal), upper shaft pressure cap, dust pan, axle, lubricating cup.Wherein, lower axle pressure cap is used for fixing lower axle
Bearing outer-ring, lower oil scraper ring and the shaft shoulder fix lower bearing inner ring, and lower oil scraper ring is fixed by round nut, and upper oil scraper ring and the shaft shoulder are fixed
Bearing, the dust pan at upper bearing (metal) is fixed on axle by round nut.Open up peace at upper shaft pressure cap and bearing block lower bearing
The hole of charge of oil cup, for lubricating metal (upper.
Bearing block is integrally located above base plate, and lower bearing is located in bearing block, and inner ring is connected on axle, lower axle pressure cap position
Below lower bearing, in it, felt collar is installed, lower oil scraper ring is located above lower bearing, upper bearing (metal) is located above bearing block, upper gear
Oil ring is located at below upper bearing (metal), and upper shaft pressure cap is located above upper bearing (metal), is connected with bearing block end face, and dust pan is located at upper bearing (metal)
Above upper shaft pressure cap.
Work process：
Submerged pump work before, need at the lubricating cup near metal (upper to bearing block in inject certain grease, fully
Lubrication metal (upper.Lower axle bearing outer-ring is supported by axle and lower oil scraper ring by lower axle pressure cap and bearing seat supports, inner ring；Upper bearing (metal)
Outer ring is supported by bearing block and upper shaft pressure cap, and inner ring is supported by lower oil scraper ring and dust pan.
Beneficial effect：
A kind of submerged pump bearing-transmission structure that this utility model is adopted, has redesigned the knot at metal (upper
Structure, Selection of Bearings optimization, upper bearing (metal) adopts single cylindrical roller axle from the angular contact ball bearing being placed back to back, lower bearing
Hold, from when strengthen the bearing capacity of bearing；The steam entrance bearing block producing in pump chamber can not be discharged in time and can be produced relatively
Big pressure, damages lower bearing, for avoiding this situation to occur, devises sealing structure at lower bearing, reduces pump intracavity gas
Collect into bearing housing and also reduce in the impurity entrance pump housing simultaneously, enter in bearing housing if any a small amount of, below bearing block, be provided with window
Mouthful, the steam producing in pump chamber can be made to discharge；For optimizing electric machine support upper end Vibration Condition, electric machine support carries out structure on the whole
Optimize, eliminate at upper bearing (metal) the structural changes such as bearing insert part solve the pump vibration occurring in traditional design structure big,
Bearing is fragile, bearing abnormal noise the problems such as, improve the service life of pump, decrease the maintenance cost of pump.This structure is simple, real
With, low manufacture cost, part is easy to process.
